Cloudflare, a web infrastructure and website security company founded on September 27, 2010, is celebrating its eighth birthday by launching Encrypted SNI (ESNI), a new protocol designed to enhance the privacy of internet users. The protocol aims to address the Server Name Indication (SNI) loophole that allows ISPs and other network observers to see which websites users visit even when they are using HTTPS-encrypted connections. ESNI is supported by Cloudflare, Mozilla Firefox, Apple, Fastly, and other industry players concerned about internet privacy. The protocol is expected to become mainstream in the coming months as more browsers add support for it.
